Ingredient Notes

Here’s an overview of the few ingredients needed to make this casserole. Be sure to scroll down to the recipe card at the end of the post for the exact measurements.

Rotini – Or any other similar pasta. I recommend a short pasta with texture that the sauce can cling to.
Marinara sauce – I like to use my homemade marinara sauce, but a jar from the store works too.
Italian seasoning – Adds flavor to the sauce.
Chicken – Rotisserie chicken works great for this recipe, but you can also use any cooked, shredded chicken you have on hand.
Cheese – I use a mixture of shredded mozzarella and grated parmesan. I highly recommend shredding and grating the cheese yourself for the best flavor and melt.
Panko breadcrumbs – If you don’t have panko, regular breadcrumbs can be used, but panko gives it a crispier topping.
Melted butter – For the crispy panko topping.
Basil – An optional garnish.

Add the topping. Combine the panko breadcrumbs, butter, and salt. Sprinkle evenly over the cheese layer.
Bake. Cover with foil. Bake for 20 minutes then remove the foil and bake for an additional 10 minutes. The cheese should be melted and bubbly and the breadcrumbs golden brown.
Enjoy. Let the casserole rest for 5 minutes. Garnish with fresh basil before serving.

Recipe Tips & Tricks

Here are a few general tips and tricks for preparing this chicken parmesan casserole recipe for the first time.

Don’t overcook the noodles. Be sure to cook the rotini to al dente and not any longer. It will continue to cook in the oven and you really don’t want mushy noodles.
Add more cheese. For extra cheesiness, add more mozzarella or mix in some shredded provolone or fontina cheese.
Stir in some veggies. For extra flavor, stir in sautéed mushrooms, onions, spinach, or diced bell peppers with the pasta mixture.
Try it with breaded chicken. Feel free to swap the shredded chicken for diced breaded chicken, such as cut up chicken patties. It’ll give the casserole a different texture and the sauce absorbs nicely into the breading.

Serving Suggestions

To turn this chicken parmesan casserole into a complete meal, I often serve it with a fresh salad or some roasted veggies. We particularly like to serve it with wedge salad, Olive Garden salad, or roasted asparagus.

How To Store & Reheat Leftovers

Fridge: Store leftover chicken parmesan casserole in an airtight container in the refrigerator for up to 3 days.
Reheat: Reheat in the oven at 325°F (160°C) until warmed through, or in the microwave in 30-second intervals.
